The technique of the regional renogram and of the conventional renogram was applied to a group of 100 patients with known hypertension, and the results of the two tests were compared. The regional renogram revealed more changes of renal function than the conventional renogram. Twenty-three of the 100 patients exhibited unilateral abnormal regional renogram; ten of the 100 patients exhibited unilateral abnormal conventional renogram. The ten patients with abnormal conventional renogram had similar changes noted by the regional renogram. The latter is probably the more sensitive screening test.

A small group of 23 patients had had both regional renogram and renal arteriogram. There may be a better correlation between the regional renogram and the renal arteriogram than between the latter and the conventional renogram.
